Site-selective synthesis of arylated pyridines by Suzuki–Miyaura reactions of 2,3,5,6-tetrachloropyridine

Site-selective arylation of commercially available 2,3,5,6-tetrachloropyridine has been accomplished, using the Suzuki–Miyaura reaction. The reaction conditions were thoroughly optimized, allowing the selective synthesis of mono-, di-, tri- and tetraarylated pyridines in good to quantitative yields. In addition, we studied the electrochemical properties of selected tetraarylpyridines by DPV-measurements.
